DeepSeek V4 Flash, Running in MoClaw
DeepSeek V4 Flash is what MoClaw's Fast tier runs: 1M context, agent-tuned, about a third of V4 Pro's price. Pick Fast, type a task, go.
MoClaw is an independent managed AI computer where you can run frontier models with no setup or self-hosting.

What DeepSeek V4 Flash Is Built For
The kind of work DeepSeek V4 Flash is made for.
The work you do fifty times a day
Triage, drafting, renaming, reformatting, pulling one number out of a long page. Flash is fast and cheap enough that you stop rationing it, which is most of the value.
Try itExecution, after someone else plans
A pattern that shows up constantly on developer forums: plan with a heavy model, then hand the mechanical edits to Flash. It scores 82.7 on Terminal Bench 2.1, so it holds its own once the plan is clear.
Try itLong inputs without the flagship bill
Same 1M-token context as V4 Pro, at roughly a third of the price and five times the concurrency. Long transcripts, big exports, whole repos.
Try itJobs that run while you sleep
Schedule it on MoClaw's cloud computer and the machine stays up whether or not your laptop does. Overnight scrapes, morning digests, weekly reports.
Try itHow it works
3 steps to wire up DeepSeek V4 Flash, no engineering required.
- 1
Pick Fast in the model picker
Fast is DeepSeek V4 Flash. There's no key to paste and no DeepSeek account to create; MoClaw handles the provider side.
- 2
Give it a task, not a prompt
Flash runs on a real computer here, so ask for the outcome. Read these files, check that site, put the result in a spreadsheet.
- 3
Move up a tier when it stalls
If a task needs more reasoning, switch tiers mid-thread. Files, history, and context carry over.
Why DeepSeek V4 Flash Is MoClaw's Fast Tier
What is DeepSeek V4 Flash?
DeepSeek V4 Flash is the smaller, faster half of the V4 family, and it went GA on July 31, 2026 as build DeepSeek-V4-Flash-0731. DeepSeek kept the preview's architecture and size and re-ran post-training, which is why the capability jump surprised people: on DeepSeek's own numbers the GA Flash beats the V4 Pro preview across the agent benchmarks it published.
It carries the same 1-million-token context window and 384K output ceiling as V4 Pro, the same thinking and non-thinking modes, tool calling, JSON output, and the same OpenAI- and Anthropic-compatible endpoints. Like the rest of the family, it has no vision input.
DeepSeek V4 Flash benchmarks
DeepSeek published Terminal Bench 2.1 at 82.7, DeepSWE at 54.4, NL2Repo at 54.2, CyberGym at 76.7, and Toolathlon-Verified at 70.3. For a model at this price that is an odd set of numbers to be looking at, and the developer reaction reflected it: on Hacker News, more than one person described Flash 0731 as the bigger leap of the two releases, and V4 Pro's GA a fortnight later as the quieter one.
All of it is vendor-reported. DeepSeek did open-source the agent framework it benchmarked with, DeepSeek Harness, under MIT as a developer preview, so the scaffolding is at least public.
DeepSeek V4 Flash pricing
As published, Flash is $0.14 per million input tokens on a cache miss, $0.0028 on a cache hit, and $0.28 per million output. From 16:00 UTC on August 16, 2026 the V4 family switches to peak and off-peak billing: Flash lands at $0.44 in and $1.32 out at peak, and $0.22 and $0.66 off-peak, with peak defined as 01:00 to 04:00 and 06:00 to 10:00 UTC.
The concurrency limit is 2,500 against V4 Pro's 500, which matters more than the price for anything batch-shaped.
Running DeepSeek V4 Flash on MoClaw
On MoClaw, Flash is the Fast tier. Pick Fast in the model picker and you are running DeepSeek V4 Flash on a managed cloud computer: a persistent file system, a browser that keeps its session, a shell, scheduling, and 50-plus skills already connected. DeepSeek runs platform-managed here, so there's no DeepSeek account to open, no key to store, and no peak-hour clock to reason about. Plan credits cover it.
Switching is one click. Start something on Fast, decide it needs more depth, and move the same thread to a heavier tier without losing your files or history. That is the shape most people actually work in: cheap model for the volume, expensive model for the hard part.
Where Flash stops making sense
It isn't the model for a task where being wrong is expensive and you won't be checking. Developers who use DeepSeek heavily tend to say the same thing: it earns its price when you steer it, and they don't hand it fully autonomous work they can't verify. Anything image-based is out entirely. For long-horizon autonomy on a codebase you care about, reach for a heavier tier and let Flash do the parts you can check at a glance.
DeepSeek V4 Flash on MoClaw vs the DeepSeek API
Pick the one that fits how you use AI.
| MoClaw (Fast tier) | DeepSeek API direct | |
|---|---|---|
| Setup | Pick Fast. That's the whole setup. | Account, API key, prepaid balance, and your own client code. |
| What it can touch | Browser, files, shell, schedules, and 50-plus skills. | Text in, text out. Tools are yours to build. |
| Billing | Plan credits, no peak-hour rates to plan around. | Per token, split into peak and off-peak from August 16. |
| Moving to a stronger model | Switch tier mid-thread, keep the files and history. | Different provider, different endpoint, different bill. |

FAQ
Quick answers about pricing, privacy, and limits.
- What is DeepSeek V4 Flash?
- The smaller model in DeepSeek's V4 family, GA since July 31, 2026 as build DeepSeek-V4-Flash-0731. It keeps the 1M-token context window and 384K output ceiling of V4 Pro, supports thinking and non-thinking modes and tool calling, and costs roughly a third as much.
- Can I run DeepSeek V4 Flash on MoClaw?
- Yes. Flash is the model behind MoClaw's Fast tier. Pick Fast in the model picker and DeepSeek runs on your MoClaw cloud computer with a browser, files, a shell, and scheduling already connected. No DeepSeek account and no API key.
- How much does DeepSeek V4 Flash cost?
- On DeepSeek's API it's $0.14 per million input tokens and $0.28 per million output, moving on August 16, 2026 to $0.22/$0.66 off-peak and $0.44/$1.32 at peak. On MoClaw it runs on plan credits, so there's no per-token metering and no peak-hour clock.
- Is V4 Flash good enough, or should I use V4 Pro?
- For volume work with a clear plan, Flash holds up: 82.7 on Terminal Bench 2.1 against Pro's 87.9. Pro pulls ahead on the long autonomous runs, particularly on DeepSWE where it scores 62.7 against Flash's 54.4. A common pattern is planning on a heavy model and executing on Flash.
- Does DeepSeek V4 Flash handle images?
- No. The V4 family has no vision input, so screenshots and scanned documents need a different model for that step.
- Do I need a DeepSeek API key for the Fast tier?
- No. DeepSeek runs as a platform-managed route inside MoClaw. There's no key to paste, no balance to top up, and no separate provider invoice.
- What is the context window on DeepSeek V4 Flash?
- One million tokens in and up to 384K out, the same as V4 Pro. Long transcripts, whole repositories, and large exports fit in a single pass.
- Can I switch away from Flash mid-conversation?
- Yes. Move the thread to a stronger tier whenever a task needs more reasoning; your files, history, and context follow. Most people run cheap for volume and switch up for the hard part.
